The fluidizing bed does not have a distributor and fluidizing gas is passed through the fluidized bed at a flow rate to fluidize the fine layer particles but not to fluidize the coarse layer. Preferably, the fluidized bed is a heat treating furnace, the fluidizing gas is combustible and objects to be heat treated are fed through the fluidizing chamber on a continuous basis. A method of operating a fluidized bed is also provided.
